Châlons Vatry Airport (XCR/LFOK) is a regional airport located near Vatry, approximately 85 kilometres east of Paris, in the Marne department of the Grand Est region of France. Originally a French Air Force base, it was converted for civilian use and has since positioned itself as an alternative freight and charter airport serving the greater Paris and northeastern France area. The airport has invested in cargo infrastructure, attracting logistics operators and freight carriers due to its uncongested airspace, 24-hour operations capability, and proximity to major motorway networks. It has also served as a base for low-cost and charter passenger operations at various points in its history. While it remains relatively small in terms of scheduled passenger traffic, Châlons Vatry plays a meaningful role in the regional cargo ecosystem and has been used for aircraft maintenance, parking, and storage operations.
